Question
Use the image to answer the question.
An illustration shows a cube placed on the top and center of a larger rectangular prism. The length and width of the prism is 6 inches respectively and 2 inches high. The sides of the cube are 2 inches.
What is the volume of the composite figure?
(1 point)
in.3
The volume of the composite figure is 64 in.3.
To calculate this, we first find the volume of the rectangular prism: 6 inches x 6 inches x 2 inches = 72 in.3
Then, we find the volume of the cube: 2 inches x 2 inches x 2 inches = 8 in.3
Finally, we add the two volumes together: 72 in.3 (prism) + 8 in.3 (cube) = 80 in.3
Therefore, the volume of the composite figure is 80 in.3.
